“…It was observed that PAPR will reduce with increase in filter roll-off. The PAPR performance of SC-FDMA-CDMA and OFDM-CDMA was compared for a frame length of 100, Spread length of 16, for 8 users with 1000 data blocks .The PAPR of SC-FDMA-CDMA was found to be lower than OFDM-CDMA Fig-7: PAPR performance of SC-FDMA-CDMA and OFDM-CDMA [16] 6.

In this paper, a survey on different modulation schemes having lowest peak to average power ratio (PAPR) value for use in uplink communication has been studied. OFDM has become the popular modulation choice for high data rate wireless communication systems. It can provide multi-path delay spread tolerance and is robust to channel dispersions. But one of the major limitations of OFDM is the large variation in signal amplitude which gives it a high PAPR. OFDM signals with high PAPR will suffer from nonlinear distortion due to non-ideal behavior of High Power amplifiers as well as it is detrimental to battery powered devices like mobile phones which are power limited .SC-FDMA was found to have a better PAPR reduction than OFDMA and has become modulation choice for uplink communication in Long Term Evolution (LTE).

Summary Technologies are advancing at a rapid rate in the current era. People are advancing with the advancement of technologies, be it in education industry, health industry, and providing luxury. With the advent of autonomous luxury‐in‐motion car that provides in‐car‐entertainment (ICE), vehicular communication is the prerequisite towards achieving this goal. Dedicated short range communication (DSRC) is a matured vehicular communication standard, and Long‐Term Evolution (LTE) is the most competing technologies in the cellular communication. In this paper, we focus on the uplink performance of the LTE‐DSRC hybrid infrastructure. The basic transmission scheme for uplink direction is based on single carrier transmission in the form of discrete Fourier transform (DFT)‐spread Orthogonal Frequency Division Multiplexing (OFDM) with a minimum mean square error (MMSE) receiver at the LTE Evolved Node B (eNodeB) and a DSRC OFDM transmitter. A comprehensive bit error rate (BER) performance simulative study has been made on a color image transmission in uplink hybrid LTE‐DSRC system, and the results obtained are encouraging that the proposed convergence is possible, as it provides a substantial decrease in the BER with a gradual increase in the signal ‐to‐ noise ratio Signal to Noise Ratio (SNR).

“…Towards this direction, a similar work can be found in [18]. In 2016, Tsiropoulou et al [19] studied and examined Until now, most of the previous works on the single-carrier frequency division multiple access (SC-FDMA) have been carried out for uplink communications in the long-term evolution (LTE) technology of mobile communication systems [8][9][10][11][12][13]. As an alternative to the orthogonal frequency division multiple access (OFDMA), SC-FDMA has drawn considerable attention in mobile communications.…”

Since the communication link of an unmanned aerial vehicle (UAV) and its reliability evaluation represent an arduous field, we have concentrated our work on this topic. The demand regarding the validity and reliability of the communication and data link of UAV is much higher since the environment of the modern battlefield is becoming more and more complex. Therefore, the communication channel between the vehicle and ground control station (GCS) should be secure and provide an efficient data link. In addition, similar to other types of communications, the data link of a UAV has several requirements such as long-range operation, high efficiency, reliability, and low latency. In order to achieve an efficient data link, we need to adopt a highly efficient modulation technique, which leads to an increase in the flight time of the UAV, data transmission rate, and the reliability of the communication link. For this purpose, we have investigated the single-carrier frequency division multiplexing (SC-FDM) modulation technique for a UAV communication system. The results obtained from the comparative study demonstrate that SC-FDM has better performance than the currently used modulation technique for a UAV communication link. We expect that our proposed approach can be a remarkable framework that will help drone manufacturers to establish an efficient UAV communication link and extend the flight duration of drones, especially those being used for search and rescue operations, military tasks, and delivery services.
